just bought couple of hours later and didn't realised and looked at my bill :) yes its a glitch, I can confirm that.

Surprisingly they charged me two different rates for same liquid (lemon) £1.43 & £1.40 and then they took off £0.83 twice, so the total was 1.17 and that equates to £0.585 slightly more but still bargain.

Tesco Pricing seems to be all over the place at the moment. Chicken Basics Ready Meals were showing as £2.78 each or buy 2 for £6, yesterday. I pointed it out to one of the shelf stackers, as they were packing the shelf next to it, but they didn't seem to give a toss (I'm not sure the girl's maths was that good!).

Same thing happened on the Mixed Fruit Salads, £1.25 each or 2 for £3, several weeks back. Would have been interesting to see what the checkout made of it. Would this apply as a pricing error under their terms, so you get the items (buying two) free anyway?

Its because the product has previously been a higher price (making the 2 for price make sense), Tesco have now made the individual price cheaper but not updated the shelf label to reflect the change.

Just a helpful word
There are different variaties but some of the bottles are 740ml some lower depending on variety, unless your going for the anti bacterial ones (blue) just stick to the bigger bottles so you get more bang for your buck

just got back from my local, and its still taking off the discount twice.worked out at 57p or 58p per bottle, depending which one you get. (the lemon is £1.43 each = 57p each after discount, the original is £1.40 each = 58p each after discount) Both bottles are 650ml. HTH.

It works for different sized bottles
Just check online which ones are marked in the 2 for 2 pound promo and add to your basket online and see what the price works out to be as it's different prices for different varieties

It was shown as £2.78 | 2 for £6 on the shelf label (and more than once for products in range) + individually priced on stock

A another way of looking at it - Tesco have made the individual prices prices more expensive to £3.50, but certain items are still the old price of £2.78. (There's not much getting cheaper in Tesco at the moment)

Seems to be a lot of size / weight+price changes going on. Another product in the range showed this label too, but the product itself was now 396g in weight (previously 368g I think), but now individually priced at £3.50, though still showing £2.78 | 2 for £6 on the shelf label.

Just hope this isn't Tesco's 'new thing' - as the Chief Executive Terry Leary has left.

Seems Tesco are attempting to confuse the customer so much, that they'll just stick the items in the basket, in fairness Tesco do have the clearest labeling of any of the supermarkets - black on white, and generally on the whole- the prices shown are correct, in my experience. Cooperative often have pricing errors on change-over day (Wednesday where I am).
